What I want to do is get the index number of a specific layer. For example, I want to look for the layer named 'Water' and I want the script to tell me "Water' is at position 50, so I know to look for it at the bottom on the TOC. How can I do this?

Enumerate pointed me in the right direction. I just had to add a conditional if statement to do what I wanted to do - find the position of a specific layer... if lyr.name == "Land Use": before the print line.
